Signature is not set as default in Outlook

This article is meant for users of CodeTwo Email Signatures for Email Clients. This software has been discontinued. If your organization uses Office 365, check out CodeTwo Email Signatures for Office 365.

Problem:

Despite setting an appropriate option in the CodeTwo Email Signatures for Email Clients application, the signature is not set as a default one in Outlook. This happens in a case when the Outlook profile has been created by a third-party software, such a G Suite Sync for Microsoft Outlook (GSSMO) (formerly Google Apps for Microsoft Outlook a.k.a. GASMO) which did not properly modify Windows Registry. As a result, you need to manually include the signature while composing a message. 

Solution:

You may configure your Outlook to include the signature automatically, by manually setting up relevant registry keys. Please follow all steps below:

1. Open the Administration Panel of CodeTwo Email Signatures for Email Clients and edit the policy that should be default.
2. Navigate to the Signature template tab. Note down the Signature name.
   Fig. 1. Signature name which is required later while modifying Outlook configuration.
    
3. On the machine equipped with Microsoft Outlook, open the Registry Editor.
4. Navigate to the one of the following keys, depending on your environment:

   HKEY_CURRENT_USER\Software\Microsoft\Office\x.0\Common\MailSettings 

   or

   HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\x.0\Common\MailSettings

   The x.0 value depends on the installed Outlook version. For an example, it would be 16.0 for Outlook 2016.

5. Create a new expandable string value entry (REG_EXPAND_SZ) with name NewSignature. As a value set the name you have noted in step 2.
6. Create a new expandable string value entry (REG_EXPAND_SZ) with name ReplySignature. As a value set the name you have noted in step 2.
7. Restart Microsoft Outlook.

From now, your signature should be automatically included while either composing a new message or replying on a existing message.
